...The term trace analysis is used to distinguish the latter. In chemical analysis, samples are conveniently divided into macro analysis (up to 0.1g or more), semimicro analysis (10-20mg), micro analysis (up to 1mg), and ultramicro analysis (up to 1μg) depending on the amount of sample handled. Microanalysis was systematized by Austrian chemist Friedrich Peter Emich (1860-1940) around 1926, but major contributions include the development of organic microanalysis by F. Pregl and the development of the spot test by Fritz Feigl (1892-1971). *Some of the terminology explanations that refer to "semimicro analysis" are listed below.

…とくに後者を区別する場合には痕跡分析trace analysisという用語を用いる。化学分析では取り扱う試料の量により,常量分析macro analysis(~0.1g以上),半微量分析semimicro analysis(10~20mg),微量分析micro analysis(~1mg),超微量分析ultra micro analysis(~1μg)などと便宜上分ける。 微量分析法は1926年ころオーストリアの化学者エーミヒFriedrich Peter Emich(1860‐1940)により系統化されたが,F.プレーグルによる有機微量分析法の開発や,ファイグルFritz Feigl(1892‐1971)による点滴分析法spot test(斑点分析)の開発などが大きな貢献をしている。… ※「semimicro analysis」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
